The process of screening and treating stale garbage

Pre treatment: Firstly, pre treat the aged garbage, including removing large non recyclable materials such as stones, concrete, etc. This step usually requires the use of a crusher or pulverizer.

Preliminary screening: After pre-treatment, the garbage enters the screening equipment for preliminary screening, usually using equipment such as bar screens and drum screens to separate the garbage into materials of different particle sizes.

Magnetic separation: using a magnetic separator to separate metal substances such as iron, steel, etc. from garbage.

Wind sorting: Separate lightweight materials (such as plastic, paper, etc.) from heavy materials (such as bricks, stones, etc.) through a wind powered sorting machine.

Optoelectronic sorting: For small materials, photoelectric sorting technology can be used for further purification, such as using infrared light, X-ray and other technologies to distinguish plastics of different materials.

Final disposal: For the remaining non recyclable materials after screening, they can be disposed of by landfill or incineration, and the specific choice needs to be determined according to local environmental regulations and standards.

Possible challenges that may arise during the processing include:

Equipment malfunction: The screening equipment may malfunction, affecting processing efficiency. The solution is to regularly maintain and inspect the equipment to ensure its normal operation.

Inaccurate garbage classification: Due to the complex composition of stale garbage, it may lead to inaccurate classification. The solution is to improve the accuracy of screening equipment and combine manual inspection to ensure the accuracy of classification.

Environmental pollution: During the treatment process, pollutants such as noise and dust may be generated. The solution is to adopt sound insulation measures, install dust collection systems, etc., to reduce the impact on the environment.

In summary, the screening and treatment of stale garbage is a complex process that requires the coordination of multiple equipment and technical methods. During the processing, it is necessary to pay attention to complying with relevant environmental regulations and standards, and take corresponding solutions to potential challenges.
